Ten cube pyrite group {100}. Overall size: 195 mm x 170 mm x 148 mm. Longest edge: 55 mm. Weight: 3.9 kg. Extracted in 1984-1985. Most of the crystals had to be reattached in the original position since in that deposit they usually become loose when extracted.

Wulfenite lenticular crystal. Size: 28 mm long x 27 mm wide x 14 mm thick. Weight: 27 g. It has some interest only for local collectors. Acquired from the shop 'Museu Areny' in Barcelona for €0.18 (about €6 adjusted for today's value) in 1962, so we can say the specimen had been field collected before that year.

Wulfenite tabular crystals with fluorite, and acicular crystals of mimetite(?). Size: 38 mm tall x 20 mm wide. Weight: 27 g. Joaquim Folch said this was the kind of crystals that were found in the beginning of the works. It has some interest only for local collectors. Acquired in 1966 from Francesc Coma i Molist, former curator of the Folch collection.

Wulfenite irregular crystals on fluorite. Overall size: 33 mm x 29 mm. It has some interest only for local collectors. Acquired by trade from a friend in 1966, so we can say the specimen had been field collected before that year.

According to the opinion of Jordi Fabre this specimen seems to be too old for coming from the 'Filón Josefa-Veneros', where a lot of famous and classic pieces were found, although its provenance is indubitable: La Collada.

Spessartine garnet crystals covering the surface of black opaque quartz crystals. Curiously only the faces of the prism, not the tips, are covered. It may be considered a floater: the base was broken by tectonic movements perhaps many millions years ago, and then a second generation of quartz recrystallized on the fracture. Size: 105 mm x 75 mm. Weight: 510 g.

Pyrargyrite crystals with a hexagonal prismatic habit. The surface color is black to dark red. Also dark red by translucency. Curiously the prisms seem to be hollow, as can be seen in several of them that are broken on the back of the specimen. Overall size: 30 mm x 19 mm. From a 19th century collection.
